With an American flag draped over his coffin, Rocco's body was escorted out of the Pittsburgh Veterinary Specialty Emergency Center on Camp Horne Road Thursday night by his fellow officers while others stood close by and saluted the K-9.

With an American flag draped over his coffin, Pittsburgh police K-9 Officer Rocco received full police honors Thursday night as his body was escorted out of the veterinary clinic where he bravely battled severe injuries the past two days.

John Lewis Rush, 21, was being held in isolation in the Allegheny County Jail on $1 million cash bond following his arraignment Friday on charges including aggravated assault, cruelty to animals, disarming a law enforcement officer resisting arrest and attacking a police dog, which is a third-degree felony.

Rush was wanted by the county for an alleged probation violation and failing to comply with Megan's Law registration when police say he stabbed the 8-year-old dog as officers tried to arrest him Tuesday night in Lawrenceville.

According to the criminal complaint, police first tried to stop Rush on Butler Street but he allegedly punched a county sheriff's deputy and tried to take his gun before fleeing.

After Rush was cornered in the basement of a nearby house, Officer Phil Lerza told him three times to give up or the dog would be released, according to the complaint. Rush lunged first, jumping at Rocco with a knife and stabbing the K-9 repeatedly, police said in the complaint.
